The tiret and up permost set of gradnations on the chart, as Shown at 8, :i 1e veight graduations and are divided into pounds and ounces. the grredurunningl 'from zero to ten pounds. which is the capacity of the present scale. The second set of graduations which nre ar ranged innnediatelrv7 below the weight grradnations. as shown at S). compriS-ies Y' l e of A`e'rzuluations representino dei; numbers. These index nn tiene extend, -i the present one to seventyT inclusive Ure printed on the chart in a diff raii (t color Vthe Weight or' the mass7 and that graduation from the other indications so as to be readily distinguishable therefrom. The third set of graduations, which occupies the body or the chart7 consists of a plurality of series oil graduations, as shown at l0E these graduations representing numbers of units and being utilized to determine and indicate the number of units in aiy load placed upon the sca'le.

The movable indicator arm 6 is 1prov' with longitudinally etendinggj series o dei; numbers corresponding to the se index number jraduationstl i adjacent to the respective unit number graduations l0 on the body o1e the chart, there being` in the present instancei'serenty series of unit number graduations. To select or determine the index number to be used in effect-ingl a computation, or count movable member of the count-ing' or indica ing' device is automatically ac'i-uttedy bj means controlled by a unit of the articles be counted to cause the indicator Wire 'l' to intersect the series oi"- index number graduiu tions 9 at a point correspon lin;` to the Weight ot' the unit. rlhe index nuniber on the indicator arm which corresponds to the index number so selected determines the readingline or series of unit number graduations on the chart upon which tbe comontation is to be made. enect a con' nu tion, or count7 the movable member of the computing` device is also actuated by means controlled by the load7 consisting of trie in of articles to be counted, and is thus moved over the chart a distance correspondinor to of the series or' graduations correspondi L to the index number, Which is intersected by the indicator Wire will represent the niunber of units in the mass or articles on the scale.

Other means may be provided determining the index number. in the pre apparatus I have included trio means for determining this number either of which ma be used at the option or convenience of! operator. The second means ior deteii ing the index number consists or" a sn line ll intersecting the several seriesvoi number graduations and so arranged 'ein the index number on the indicator which i adjacent to the point at which the indicator intersects the spiral line ll will constit'it the index number to be used in making th computation. The arrangement is such that the index number so selected by the spiral line corresponds exactly with t'ne index nun ber which is selected on he series or' inde Vnumber graduations 9.

In the present instancej i here utili'fed a hed by lhe unit controlled for aut matically actuating the movable member of the computing device to determine the inde); number, and the load controlled means for automatically actuating' said moral-ole member to effect a computation or count may take rarious forms but, in the present mcchanisr i have provided a unit balance torselef j; the index number which i: entirely "ce trom the load balance e indicator to eitect the upon that indexY number. 1ere "n, the uiit balance comprises u ma Y ler-cr which is carried by a pivot l inoruted in suitable bearis on ugcarried the .base l.

A platform holder' 3T is mounted on the main lever 3st Which is here shown as provided with bearings to engage a lmife edge pivot 3S rigidly secured to that lever. This holder is adapted to support a suitable platform or load receptacle to receive the mass of parts to be counted. The platform holdcr is retained in its proper horizontal position by means of a stem 2li) extending dou" Wardly therefrom and connected by a link -fxtl t0 a stem Lil projecting from the lower ide of the base l. The longer end of the main lever extends into the housing and provided with a nose bar having a needle point i3 to engage a bearing in a stirrup 441-, Which stirrup is connected with a liexible ribbon or strap the upper end of which is secured to and extends about a cam et. This cam is mounted upon a shaft si journaled in bearings 48 and il@ mounted respectively in the cross bars 3 and si and. arranged in co-axial alinemcnt with the shaft 2i of the unit actuated cam 18. Trie cam eit is preferably adjustable with relation to the shaft and, as here shown, is adjustably but rigidly secured to a hub member in the same manner that the cam 1S is secured to the hub member 24. A pendulum provided to serve as a counterbalance for the W io'ht of a load placed in the load receptacle, and, as here shown, pendulum rod 5i is rigidly secured to the hub member 50 and a Weight 52 is rigidly but adj ustably secured to that rod by means of a set screvf rhe outer end of the lever Se of the load balance is provided with a balance weight, as shown at 54, to maintain the proper tension on the ribbon when there no load on the platform of the scale. The load balance is also provided with a dash pot to check the vibrations thereof. The cam ett of the load balance connected with the indi ator (i so that that indicator Will be actuated by the load balance. The connection is of such a character that the indicator may be actuated by the unit baiance inde? A, t or the load balance. To this end I have secured to the pendulum rod an arm 5G which extends across the pendulum rod of the unit balance and is provided with an adjustable screw 57 to the pendulum rod 2S and thus cause the hub 2e and the cam i8 to move With the hub 50 and cam Lib of the load balance. thereby actiuitingff the indi-- cator arm t3. Each of the c has center of gravity established that, as the cam is adi usted circinnferentially when sealing the nicchanisi of gravity of the corresponding pnduluni will not be shifted by the '-:aried p tien of the cam. To this end each cam is provided with an adjustable 'weight by means of Which its center of gravity may be established. The hub member by the lead actuated mechanism is provided `with a proto limit the movement of the hub members 5t) and 2li in the opposite direction.

In the operation of the scale to count the.

number of articles in a mass of like articles y a unit consisting of one or more of said articles is placed in the unit receptacle 16, thereby causing the unit balance, through its cam 18 and independently of the load mechanism, to actuate the indicator G and cause that indicator to indicate on the series of index number graduations 9, and on the spiral line 1l when the latter is used, an index number. The index number having been noted the unit is removed from the unit receptacle and the mass of articles to be counted is placed on the load platform, thereby actuating the lever 34 and the cam it and through the connection between the cam etti and the cam 18 actuating the indicator G and moving the same into a position corresponding tothe weight of the load. The position of the selected index number on the indicator determines the reading line, or the particular series of unit number graduations to be used in effecting the computation, and the particular graduation, of that series of unit number graduations, which is intersected by the indicator represents the number of articles on the load platform. If it is desired to count out a specified number of articles the index number is selected in the same Way and articles are poured onto the load platform until the indicator indi- Cates the desired number on that series of unit number graduations corresponding to the selected i ndex number. If the unit consists of a single article the number of the graduations intersected by the indicator represents the number of articles in the load or mass which is being counted. If the unit consists of a plurality of articles then it is necessary to multiply the, number of the intersected graduation by the number of articles in the unit to determine the number of articles on the load platform. For example, if the unit contained ten articles and the indicator intersected the graduation numbered in the proper series of unit nuniber graduations, this number 3DO woul d be multiplied by l0, thus indicating that there were 3900 articles on the load platform. lilhile the unit may consist of any number of pieces it preferable,` for the salte of simplicity, to use either l, l() or l0() pieces a unitI` thus enabling the multiplication to be very quickly and accurately made.

will be noted that the unit number llcn tl chart, the indi- LAD ,ions are a i ne nig only the index numbers to llt) Vin pounds and ounces.
